Lighting/Keying
Hey everyone,
hopefully you can help me out. The outdoor footage that was shot has the sky as just a blank white, (not really overexposed to the point where it is bleeding too much into the other areas, but a little bit) I was hoping you could point my in the right direction as to how to fix this. I want the backgrond just to be a solid gradient. (I know how to do that :))I’m sure it is going to take tons of work because the keying won’t work because it will mess up the rest of the footage. Do I have to do something frame by frame? And if so, will it look all chaotic rather than smooth (if i have to do it frame by frame, it will seem jumpy and ugly)… Any suggestions?Thanks

Just an idea. I tried keying out a sky from stock footage. I had limited successs, but this is what I did maybe the technique will yield better results for you. I simply made a rough mask of the sky area, and then used curves and hues and saturrationto turn the are into a hi contrast balck and white image (you made a mask to get rid of the detail of the ground or whatever isn’t sky). Put a black solid underneath and precompose. Use this precomposed black and white as a luma matte for your original footage. I hope this helps, without seeing the footage its difficult to tell if its gonna work out for you. The tutorial about blemish removasl talks about making luma mattes and might be worth looking at.
